Go for Z77 with top i7 processor, 2 SSD with RAID and 1HDD for backup, at least one 27'' 3D monitor, GTX680 SLI/GTX 690. i think those components can utilize ur money properly. Don't go for X79 its just waste of ur money proportion to performance!

As expected, people saw the budget and put out whatever crazy names they could come up with.

And as ironic as it may sound, you actually have little choices if you want to fully use the money. I'll just put in some suggestions for most value (yes ironic again), other components you can decide on yourself. I will assume gaming is your priority.
GPU(s):

Don't get a 690, it's potential is limited.

Get 2x 4GB GTX680. Thermal limits and performance will easily be higher than any 690. Why Nvidia? Because SLI > CF, most reviewers have confirmed that SLI gives a smoother experience compared to CF despite it's lower average FPS. You can see for yourself here: http://www.tomshardware.com/reviews/...re,2995-5.html

It's a bit old but recent reviews of hardware confirmed the very same thing, but no graphs are provided. You can check HardOCP SLI or Crossfire GPU reviews for confirmation.

Don't just get any GTX680 though. I wouldn't even recommend EVGA ones since they use a blower cooler.

I can personally vouch for ASUS' cooler, top notch performance and very silent. You can look at GIGABYTE's Windforce offerings as well.
Monitor(s):

If you want this for work, then get 3x 1920x1080 IPS monitors.

But for gaming, get a 2560x1440 monitor instead. Because the support for Surround is poor.

These 2 things will eat up about $1900. If you need to scale back, keep the monitor but get 2x 4GB GTX670 instead. That will trim off about $100.

That's all I have for you. I would've recommended a processor but the only viable option is the 3770K, but with Haswell coming I don't want to suggest anything.

But don't overdo on the Motherboard, Casing (<$200; $150 even better), RAMs (not above 16GB) and CPU coolers. Get a decent Air cooler if you want more performance, or a Closed loop water cooler if you want more silence. High end RAMs and what not are BS, and I'm sure you won't have much use for high overclocking ability of RAMs which end up making <2% difference anyway.

Edit: Almost forgot, get a 256GB SSD and a 1TB HDD. SSD prices have dropped significantly and 240GB+ can be had for about $150.
